Laptop Case

I just bought a Dell Studio XPS 16 for $1100 and school next year and I wondered what kind of case I should get for it. I need opinions on a nice one that will certainly protect it and not be a pain in the butt to carry around, My girlfriend has a $75 case from the local computer store in my hometown for her macbook (blah) but I was hoping I didn't need to spend that much. Any great comments or cases you guys have for yours? Whatever it is it has to be able to fit 16" lappys. Thanks!
